Application led January 14, 1918. Serial No. 211,791.

To @ZZ lwhom t may concern:

Be it known that l, STANisLAw MARGIN- raii, a citizen of the UnitedStates of America, residing at Buffalo, in the county of Erie and Stateof New York, have invented certain new and useful Improvements inStone-Baking Machines, of which the following is a specification.

The primary object of the invention is the provision of a ready meansfor pickingi up stones in large quantities for transportation, thedevice being operable while being forwardly propelled over the ground.

A further object of the device is the provision of a vehicle adapted forgathering stones from the ground over which the device travels so thatlarge areas may be quickly covered in picking the stones therefrom, thevehicle being capable of carrying large quantities of stones fordelivery at a distance.

A still further object of the invention is the provision of a stonepicker in the nature of a vehicle that is strong and durable inconstruction, easy and inexpensive to manufacture and capable ofperforming the work of a large number of laborers in an expeditiousmanner.

In the drawings forming a part of this application, in which likereference characters refer to corresponding parts throughout the severalviews,

Figure 1 is a side elevation of the device,

Fig. 2 is a top plan view thereof,

Fig. 3 is a vertical longitudinal sectional view of a portion of thedevice taken transversely through the stone receiver in its lillingposition,

Fig. 4 is a similar view with the receiver in its dumping position.

Fig. 5 is a top plan view of a portion of the receiver and rake member.

Fig. 6 is a view similar to Fig. 3 including a showing of the adjacentportion of the vehicle body, and

Fig. 7 is a detail view of a portion of the receiver adjustingmechanism.

My invention being designed for picking up stones from the ground andtransferring them to desirable locations, the same broadly consists of avehicle 1() having a substantially U-shaped frame 11 arranged with ahorizontal axle 12 at its rear end with ground wheels 13 positionedthereon and with a single forwardly positioned wheel 1/1 adapted forturning in steering the device when drawn forwardly by any suitabledraft means attached to a yoke 15 positioned above the steering wheel14.

Forwardly extending arms 16 are journaled at their rear ends upon theaXle 12 while a stone receiver or drum 17 is journaled to the forwardends of the said arms by means of trunnions 18 secured to the said armswith bosses 19 at the ends of the drum journaled upon said trunnions.The drum 17 is arranged with a longitudinal opening or mouth 20 at oneside thereof adapted for positioning at the top of the drum as shown inFig. 3 during the filling operation, the drum being readily inverted asshown in Fig. l for dumping the stones from the drum 17.

A rake 21 is also journaled upon the trunnions 18, the said rake beingin the form of two rectangular frames 22 perpendicularly arranged withtheir end members 23 centrally journaled upon the trunnions 18 and withthe connecting sides 24 of the frames provided with a plurality ofsubstantially S-sliaped hooks 25 slightly spaced apart and extending inthe same direction.

A gear 26 is arrangedl adjacent each end of the aXle 12 within the framel1 and inwardly of the arms 16 in constant mesh with similar gears 27secured to the trunnions 18 and rake 21 whereby the rake is revolved inthe direction indicated by the arrows in Fig. 1 of the drawings duringthe forward travel of the vehicle 10.

Rocker arms 28 are pivoted as at 29 to th sides 30 of the vehicle frame11 and are connected by links 31 with the arms 16 while rods 32 connectthe rockers 28 with operating levers 33 arranged at opposite sides ofthe vehicle and adjacent the drivers seat 34, the latter being carriedby a forwardly arranged triangular inclined bottom or footboard 35positioned within the forward V- shaped portion 36 of the frame 11. Aspringpressed latch 37 is carried by each of the levers 33 for engagingtoothed racks 38 arranged adjacent the bottoms of the levers 33, saidlatches being operable by levers 39 in substantially the usual manner.

It will be seen that the driver positioned upon the seat 34 may controlthe forward movement of the vehicle 1l by guiding the horses, or otherdraft means attached to the yoke 15 and by operating the levers 33 mayregulate the position of the hooks 25 with respect to the ground 4G overwhich the vehicle 10 is traveling. Any stones which cla Civ

are positioned upon the ground 40 will be engaged by one or more of thefour operative side portions of the rake 2l and the stones picked up bythe same and deposited into the open mouth 2O at the Vtop of thereceiver 17. It will be understood that the receiver 17 normallymaintains its upright position by reason of its own weight and anystones which have been deposited therein and when the drinn is'filledwith stones, the saine may be inverted in emptying the stones upon theground beneath the vehicle.

A body or trailer 41 is arranged with its forward end journaled upon thevehicle axle .l2 and provided with rear ground wheels 42, the said bodyhaving an open top and provided with spaced teeth 423 in its concavedforward end @i positioned rearwardly of the drinn 17. A set screw 45 isarranged for each of the hooks for detachably mounting the hooks uponthe sides 24 of the rake. The rake hooks or teeth 25 pass through theopenings between the teeth 43 of the forward body 41 and may deposit anystones int-o the said body which remain upon the hooks after passing thedrinn mouth 20,

`while it will be understood that the teeth of the said body wall 4lserve to clean the hooks 25 from the stone during the travel of thehooks between the said teeth. The forward travel ofthe vehicle l0operates the rake 2l for gathering the stones upon the ground andelevating the saine into the drum 17 and into the body 4l, the concavedformation of the teeth insuring a release of all of the stones from therack 2l which have passed the drinn and the deposit of such stones intothe body 41.

A large track of stony ground may be quickly cleared of all stones bymeans of neet-,eis

this device, only one person being required for operating the same andsuch person postioned upon the seat 34 having complete control of thedevice.

`What I claim as new is l. A stone picker comprising a vehicle havingground wheels secured to an axle, a rotatable rake operatively geared tosaid aXle and provided with rows of hooked teeth spaced apart andprojecting' in the saine direction, manually operable vertical adjustingmeans for said rake, and a body for the vehicle rearwardly of the rakehaving a concaved forward end provided with notches forming teethadapted for the clearing passage of the rake teeth therebetween dui-ino'the operation of the device upon the forward movement of the vehicle.

2. A device of the class described coinprising avehicle frame, a rearaxle journaled in said frame, groundwheels secured to said axle,yforwardly' projecting arins journaled upon said axle, a` rotatable rakecomprising rectangular `frames journaled upon the free ends of the armsandprovided with rows of spaced engaging hooks, gear connections betweensaid rake and said axlea hand levers operativelyY connected to said armsto vertically adjust said rake, a trailer body pivotally suspended fromsaid axle rearwardly ofthe rake and provided with a notched concavedforward end forming spaced clearing teethfor said rake hooks, said hookshaving ,a path of movement between said teeth diiring the rotation ofthe rake when the device is operated, and rear ground wheels for saidbody.
